An Anticoagulant Coating Based on a Block Phosphocholine Copolymer for Potential Applications in Blood Contact Devices

Advanced Materials Interfaces, EarlyView.
Anticoagulant properties are critical for blood‐compatible materials, and anticoagulant coatings are a common key issue for blood‐contacting medical devices. In this study, a block copolymer poly(2‐methacrylenoxyethyl phosphocholine‐b‐glycidyl) (PMPC‐b‐GMA) is synthesized, using reversible addition‐fragmentation chain transfer polymerization (RAFT) and

Coronary angiography of the ex‐situ beating donor heart in a portable organ care system

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1252-1260, December 1, 2022., 2022
Abstract Objectives To determine safety and feasibility of ex‐situ coronary angiography. Background To cater for the perpetually growing demand for heart donors, interest in donation following circulatory death (DCD) has been rekindled. Further pursuit of donor pool expansion has led to eligibility extension to “marginal” donors who are at higher risk ...

Nanostructured 316L Stainless Steel Stent Surfaces Improve Corrosion Resistance, and Enhance Endothelization and Hemocompatibility

Advanced Materials Interfaces, EarlyView.
This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.
